How 911 Works

Tangi 911 System

Tangipahoa 911 is considered an Enhanced 911 system because of all the informations that is sent to our location over AT&T equipment. At the present time we are also a transfer agency meaning that we process all 911 calls and send them to the appropriate police, fire or EMS agency in our area.

The system basically works in the following manner:

The caller dials the emergency number (911) on a landline phone.

The telephone company then routes the call to our Public Safety Answering Point (or PSAP) based on the callers address.

Next when answered, the caller's information is desplayed on our computer monitors (Name, address, phone number as well as responding Police, Fire, Ems agencies.

The caller dials the emergency number (911) on a cell phone.

The telephone company then routes the call to our Public Safety Answering Point (or PSAP) based on the tower the caller is on. (Misroutes from other parishes are common in our area meaning they may be calling in an area not served by us)

At this point we will receive only telephone number and cell tower location on calls from older cell phones. Expect the telecommunicator to ask questions to determine where you are and what agency to send.

On newer cell phones and major carriers, we are now able to get a better location (still not complete) due to receiving the latitude and longitude of the calling phone.

VoIP phones are still new in the 911 arena. Some carriers may not offer service or the individual may have to enter in their own physical address. (Again expect telecommunicators to ask more questions as the party may have even moved to a different location and failed to change their address with the company).
